Manganese cycle Manganese in soils is present in three oxidation states: Mn+2, Mn+3 and Mn+4 of which Mn+2 is the primary form in which Mn is absorbed by plants. Manganese becomes plant available after release of Mn+2 into the soil solution, Mn+2 transport to the root surface by mass flow and diffusion, followed by uptake
